Abstract: PURPOSE: To enhance current efficiency, Al alloy for current passing anode to be used for cathodic protection os added with Ca, Zn, In, and Sn, and content of Cu, Si, Cu impurities is controlled.  
     CONSTITUTION: Al alloy for current passing anode is added with Zn: 2.0 to 5.5 wt%, In: 0.01 to 0.04 wt%, Sn: 0.001 to 0.04 wt%, Ca: 0.05 to 0.7wt%. Impurities are controlled to Fe<0.20 wt%, Si<0.10 wt%, Cu<0.01 wt%. Incorporating Sn, Ca, etc. into Al in the amount specified above effects that Ca is disapersed into Al alloy as solid solution, producing more uniform corrosion surface due to Zn.

Abstract: PURPOSE:To compensate the deviation of the translucent axis of a polarizer due to the azimuth and to obtain the polarizing plate and a view angle which hardly vary in polarization performance owing to the inclination by arranging the phase delay axis of a sealing film in parallel to the absorption axis of the polarizer. CONSTITUTION:The sealing film 1 is connected to the polarizer 3 so that its phase delay axis is parallel to the absorption axis of the polarizer 3. The sealing film 1 is birefringent and has a 190-320nm phase difference and the Q value calculated from Q=(nx-nz)/(nxny) is 0.1-0.9, where nx, ny, and nz are the refractive indexes in the phase delay axis direction, phase advancing axis direction, and thickness direction of the refringence. The polarizing plate 4 is arranged on one or both sides of a liquid crystal cell 4. Consequently, the variation of the translucent axis of the polarizer 3 due to the azimuth angle (tilt angle) can be compensated with the phase difference of the sealing film 1.

Title: Reference voltage generating circuit
Inventor: CHO SHIZUO
IPC: G05F3/24
Filed: 1990-04-13
Abstract: PURPOSE:To obtain the stable reference voltage by generating the 1st and 2nd reference voltage from the 1st and 2nd reference voltage circuits respectively, comparing the 1st reference voltage with the 2nd one by a comparator means, feeding back the output of the comparator means to the 1st reference voltage circuit, and outputting the 3rd reference voltage. CONSTITUTION:A 1st reference voltage circuit 40 generates the 1st reference voltage by a MOS transistor TR 42 of the 1st polarity, and a 2nd reference voltage circuit 50 generates the 2nd reference voltage by a MOS TR 52 of the 2nd polarity. At the same time, the 1st reference voltage is compared with the 2nd one and the output in response to the result of comparison is fed back to the circuit 40 by a comparator means 60 for output of the 3rd reference voltage. Therefore the circuit working delay is compensated by securing the characteristic that increases the reference voltage in response to the rise of the temperature with selection of the characteristic like the channel length, etc., of a MOS TR. Furthermore the stable output is secured since the 3rd reference voltage is decided by both TR 42 and 52 having the polarities complementary to each other. Then the stable reference voltage is obtained at a low cost.
